Abstract: A portable electronic device includes first and second housing portions pivotal about corresponding pivot axes. A biasing member urges a first cam surface of the first housing portion into engagement with a second cam surface of the second housing portion. The biasing member also urges indexing members of the first and second housing portions into engagement to maintain synchronization of the housing portions during rotation, wherein the first and second housing portions are configured in a fixed angular orientation when the first cam surface is engaged with the second cam surface.

Abstract: A handheld communication device may comprise a first housing including a first keypad, a main printed circuit board, and a battery. A second housing may include at least one display, and the first and second housings may be rotatable relative to one another. The device may comprise a hinge barrel containing a biasing member and at least one cam follower. The hinge barrel may be rotatable relative to the first and second housings.

Abstract: A portable radiotelephone (100) arrangement is disclosed. The portable radiotelephone is preferably foldable and comprises a first housing (102) and a second housing (108) hingedly connected to the first housing portion. The second housing portion has a recess for receiving a battery pack (115) and a battery cover (114) for covering the battery pack. Further, a detachable battery (2600) is coupled to the radiotelephone and covering at least a portion of the battery cover. The first housing portion of the foldable portable radiotelephone may also include a display (126) and a speaker (120). The second housing portion may further include a keypad (136) and an antenna (202).

Abstract: A wireless communication device (20) provides a matching state between a radio circuit (28) and an antenna assembly (26) in both its retracted and extended positions, and does so with an elegant design that increases reliability and manufacturability by reducing the number and complexity of components and moving mechanical parts. A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states.

A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states. Furthermore, the switch (32) can be integrally formed as part of a feed terminal (36), the feed terminal (36) and a ground terminal (38) can hold the antenna in position, and the ground terminal (38) can hold a guiding tube (52).

Abstract: A radio telephone (100) has a hinge (301) for joining a body (101) a cover (103) along an axis. The hinge (301) contains the axial force generated by an urging mechanism (403,404,405) by locating the urging mechanism (403,404,405) in a can (303) and attaching a cap (305) to the can (303).

Abstract: A battery pack containing a battery of cells includes an outer casing (402) adapted to receive a battery of cells (404); a bonding surface (410) positioned along the outer casing (402); an inner casing (408) adapted to encapsulate the battery of cells (404) and having a surface for bonding to the bonding surface of the outer casing (402); and a bond provided at the bonding surface to bond the inner casing (408) to the outer casing (402). Also, a method for forming a battery pack comprises steps of positioning a battery of cells within a bonding surface of an outer casing of the battery pack; encapsulating the battery of cells with an inner casing, the inner casing having a surface corresponding to the bonding surface of the outer casing; and bonding the corresponding surface of the inner casing to the bonding surface of the outer casing. The battery pack and method for forming the battery pack reduce the weight and complexity in manufacturing.
